5 ways to break the link between economic development and resource consumption

Efficiency-promoting policies can go a long way toward sustainably boosting growing economies.

The world is using its natural resources at an ever-increasing rate. Worldwide, annual extraction of primary materials — biomass, fossil fuels, metal ores and minerals — tripled between 1970 and 2010. People in the richest countries now consume up to 10 times more resources than those in the poorest nations.

Clearly, if the developing world is to enjoy a similar standard of living to that of the developed world, this cannot continue. We need to break the link between global economic development and primary resource consumption.

The meeting saw the launch of an international report (and summary for policy-makers) coordinated by CSIRO and the U.N. Environment Programme. The report lists several ways in which the world can maintain economic growth while reducing its primary material use — ending the pattern that has driven world economic growth over the past four-and-a-half decades.

The Importance of Decoupling

Decoupling economic growth from resource use is crucially important — especially when we consider our finding that not even the wealthiest countries have managed to stabilize or reduce their overall material consumption footprint. The only time this footprint was reduced was during the global financial crisis of 2008-09. It has since begun to grow again.

This suggests that there is no level of human well-being at which the demand for primary materials will level off — unless we make some fundamental changes to our economy.

Since the turn of the century, as emerging economies like China have begun to industrialize and urbanize, they have used massive amounts of iron, steel, cement, energy and construction materials. While this has helped millions of people move out of poverty, huge infrastructure investments have also ratcheted up the demand for primary materials to unprecedented levels.

Surprisingly, this boom in global growth has not led to improvements in efficiency, despite the many technological advances along the way. The global economy uses more material per unit of GDP than it did in 2000. This is because production has shifted from material-efficient economies such as Japan, South Korea and Europe to less efficient ones like China, India and Southeast Asia.

Decoupling will create the space for developing countries to raise their standards of living while also achieving the SDG objectives. This won’t occur spontaneously; it requires well-designed policies, not to mention large public investments in research and development.

New Measures Needed

Past policy decisions that determine economic development, human well-being and environmental outcomes have often been informed by a small set of economic indicators.

In contrast, policies designed to achieve progress towards the SDGs will require new information about natural resource use and environmental impacts. The new report, compiled with help from my colleagues in Austria, Germany and Japan, aims to provide data on current resource use, and on how these primary materials might be used more efficiently to produce goods and services.

There is no level of human well-being at which the demand for primary materials will level off — unless we make some fundamental changes to our economy.

We have found that while dramatic increases in the consumption of fossil fuels, metals and other materials threaten to intensify the effects of climate change, increase pollution and harm wildlife, there are also large opportunities to embrace more sustainable practices. This in turn would also lead to economic benefits and improved well-being.

There are many well-known ways to improve resource efficiency and decouple economic activity from growing resource use and emissions, including:

Construction and housing. Improved building materials, insulation and orientation of new buildings together can cut energy use in buildings by 80 percent. Meanwhile, using higher-strength steel in the construction of medium-density and high-rise buildings can save on the amount of construction material used.

Agriculture and food. Improving irrigation techniques, reducing fertilizer and pesticide use, reducing average consumption of meat and dairy, and reducing food loss and waste from its current level of more than 30 percent would all reduce resources needed per unit of economic activity.

Heavy industry and energy. Besides embracing recycling and renewable energy, heavy industries such as steel, cement and paper can each draw on a range of new technologies, such as electric arc furnace improvements in the iron and steel industry.

Technology. Nano- and biotechnology will play increasingly important roles in sustainable production and consumption — for instance, through the creation of more durable products or the development of enzymes as industrial catalysts.

The report recommends placing a price on primary materials at the point of extraction, as well as putting a price on carbon emissions. The proceeds of these levies should be invested in research and development in resource-intensive sectors of the economy, to find yet more ways to reduce overall consumption of materials.

Of course, increasing material efficiency can bring its own problems. The report recommends various policy initiatives to address these issues. Among these are shorter working hours to compensate for productivity gains, instead of salary increases alone, to avoid the rebound effect of higher overall consumption.

Lower-income countries will doubtless require more primary materials than they currently use, if they are to reach the same level of development as today’s wealthy countries. Expanding global demand for materials may contribute to local conflicts like those seen in areas where mining competes with agriculture and urban development. But the more we can curb the world’s resource growth, the more room there will be for people’s standards of living to grow too without surpassing planetary limits.
